just going to repost an answer to a question of "What are we going to use the NBN for/how is it going to aid us economically" on another forum:
The assumption implicit in your list is that the world is going to stop for every other technology apart from NBN. Fibre to the premises will be rolled out when and if required, but it will be a based on hard cold economics at the time of the decision rather than on a fuzzy feel good wish list many years in advance.
As I said in a previous note, you have to look at the complete end to end solution and if all your investment is tied up in the network, there may be nothing left over for the other components. What is the point of remote medical diagnosis capability in every home if it requires a nurse, say, to attach the probes, but there is no money left in the budget to hire additional nurses.
And even if the NBN can make video stores obsolete by enabling video on demand of 3D/HD movies, is that the best use of our scarce resources.
Somebody likened the NBN to putting a 4 lane toll road to everyone's house. That includes those who don't have a car, those who can't drive and those who for whatever reason prefer other forms of transport or only infrequently drive. You can also come up with a list of deliverables that the 4-lane tollway can uniquely deliver to the house, but that doesn't mean it is the right thing to do with limited resources.
